TIN-SHEET SEPARATOR.

Application filed October 3, 1921. Serial No. 505,086.

ToaZZ whom it may concern:

Be it known that I, JOHN EVANS, a citizen of the United States, residingat Toronto, in the county of Jefferson and State of Ohio, have inventednew and useful Improvements in Tin-Sheet Separators, of which thefollowing is a specification.

This invention relates to an apparatus for separating sheets of metalwhen the same have become stuck together, an object of the inventionbeing to ..provide smooth separating rolls and corrugated gripping rollsfor drawing the sheets over the separating rolls.

Another object of the invention is to provide a set of smooth rollsthrough which the sheets are fed after passing between the grippingrolls for rolling out the corrugations formed in the sheets by saidgripp ng rolls.

A further object of the invention is to provide means whereby the upperand lower spaces between the gripping rolls may be adjustedindependently 01. each other to conform to the thicknesses of the sheetspassing through said spaces.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter'fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing my invention in detail, reterence will be had to theaccompanying drawings wherein like characters. denote like orcorresponding parts throughout the several views, and in which :Figure lis an elevation, partly in section of the invention.

Figure 2 is an elevation of the opposite side.

Figure 3 is a section on line 33 of Figure 1.

Figure 4c is a longitudinal sectional view.

Figure 5 is a sectional detail view.

In these views 1 and 2 indicate the supporting frames of the apparatus,each of which being provided with the vertically extending recesses 3for receiving the hearing blocks for the rolls. The upper end of saidrecesses are closed by the top plate 4 which is held to the frame by thebolts 5, said bolts being held in place by the pins 6. The bearingblocks are shown at 7.

I provide a pair of separating rolls 8 which are of smooth contour and apair of small corrugated gripping rolls 9 and another pair of grippingrolls 10 which are also corrugated and are of considerable largerdiameter than the rolls 9. .The gripping rolls 9 and 10 are placed in avertical row with the small rolls 9 intermediate the large rolls, thebottom roll 10 contacting with the lower roll 9 and the top roll 65 10contacting with the upper roll 9, thetwo rolls 9 also contacting witheach other. Said rolls 9 are also in the same horizontal planes with thesmooth rolls 8. The rolls 9 and 9 are supported by the same bearingblocks, two sets of three blocks each being provided for "facilitatingthe placing of the rolls in position. The bottom block rests uponshoulders formed in each supporting frame and the blocks are heldagainst movement by the screws 11 which pass through the plates l andhave their lower ends bearing against the upper block. The lower blocks7 which support the bottom roll 10 are vertically movable by means ofthe screw shafts 12 engaging screw threaded sockets in the blocks andsaid shafts are connected by the gears 13 with the wrench receivingshaft 14. The bottom blocks of the sets of the intermediate rolls arerecessed, as at 15, permitting movement oi? the blocks 7. The toproll'lO is supported by the sets of blocks for the intermediate rollsand is held in place by the top block 7 which is held in place by thescrews 11 which are carried bythe plates 4. The screws 11 and 11 areprovided with wrench receiving heads so that they can be adjusted by awrench.

In rear of the rolls just described are the smoothing rolls which are oflarger diameter than any of the rolls before mentioned and are journaledin the blocks 7 X which are held in position by the screws 11*.

The sheets to be separated are placed over 100 the separating rolls 8and the end of the upper plate is passed between the upper set of rolls9 and 10 and the end of the lower plate, o plates, passed between thelower setof rolls 9 and 10. The corrugated rolls will 105 grip thesheets and cause them to pass between the rolls, thus pulling them overthe smoothin rolls 8 which will separate the plates. is the plates passbetween the cor rugated rolls they will be brought together 110 againowing to the different sizes of the corrugated rolls, so that they willbe directed between the smoothing rolls 15. These rolls 15 will take outthe corrugations made in "the plates by the corrugated rolls.

If more than two sheets are to be separated the top sheet is passedbetween the upper corrugated rolls and the space between the lowercorrugated rolls is increased to permit the passage of the remainingsheets. After the first sheet hasbeen separated the remaining sheets arepassed through, the second sheet beingplaced between the uppercorrugatedroll and this action is kept up until all the sheets areseparated. 'However, the corrugated rolls have a tendency to separatethe sheets, if they are not too firmly connected together, so thatinpassing the sheets through the lower corrugatedrolls they maybeseparated and it will not be necessary to run the group of platesthrough the corrugated rolls again.

It will be seen, that the upper and lower rolls 10 can beadjustedindependentlyso as to makethe space between them and the intermediaterolls of the proper size to receive the sheets.

The lower roll 10 is connected by the gears 16 with the intermediateroll 9 which contacts therewith and this rOll 9is connected by the gears17 with the upper roll 8.

These gears are located at one side of the apparatus andat the oppositeside a similararrangement of gears is provided for connecting the upperroll 10 with its contacting roll 91 and this rOll 9 with the lower rollA 8. Power may be applied to the large rolls .10 in any, desired manner.
